410FTB AERATION AIR FLOW METER

Wastewater applications require fast, precise control of air flow which in turn controls the dissolved oxygen (DO) in the aeration basin. Traditional control schemes result in DO measurements with large oscillations, requiring a higher DO setpoint. Large oscillations cause rapid wear of valves and other expensive system hardware while the supporting overranged DO setpoints create significant energy losses. Tighter control requires a faster, quieter measurement signal of the aeration air.

Kurz engineers created the 410FTB Aeration Air meter to allow optimization of the DO control systems. Tests confirm that the 410FTB outperforms other thermal flow meters by providing a quieter, faster response. The 410FTB was field proven with Model Predictive Control, a state of the art nonlinear control system, resulting in energy savings up to 45%.
